How safe am I?

Ok so I am buying a bike from a user on this website. His name is "slope" has been a member since 2000.I am not expecting this guy to be a scammer since his loyalty to the website, but I can't trust anyone. I am buying the bike through Paypal and am wondering how safe I am getting my money back. I have emails from his family email and his personal email. Address and Home and cell numbers. I also have emails from him sending me pictures and componentry lists. I also have 50+ messages between us regarding shipping/pickup and odds and end questions. He also doesn't have it listed on the BuySell part of the website.
